@NathWraith, allow me to ask if I want to upgrade my internal engine to support more than 250hp on my GT2-7040 supercharger, what are the specific things to do?hello mate, my car is HKS forgerd but standard cams!
I have with me the item as below,
1. HKS Forged Piston & Conrod
2. HKS Metal Head Gasket 1.2mm
3. HKS 80mm Supercharger pulley (current is 90mm pulley)
